Outcome measures
Primary outcome
The main study parameter is the use of an online diary concerning duration,
frequency and completeness of entries. Also, we will study if people adhere to
their lifestyle goals.
Secondary outcome
Secondary parameter is the influence of the subjects* personal characteristics
on the use of the online diary.
Background summary
There is an increasing number of people with overweight. Moreover, people
experience problems adhering to a healthy lifestyle. In practice, treating
overweight implies for people performing a number of treatment self-regulation
tasks, such as keeping a diary of diet and physical activities. Following
research on self-regulation, eHealth technology and personalized computer
assistance, we designed an online lifestyle diary accompanied by a personal
computer assistant that may stimulate the use of an online diary.
Study objective
Our main objective is to evaluate an online lifestyle diary accompanied by a
personal computer assistant. The assistant provides people who are overweight
feedback on their lifestyle goals. We want to study if it contributes
positively to self-regulation, i.e., use of an online lifestyle diary. We
expect that the the knowledge about and attitude towards a health ylifestyle
improves and that the subjects will adhere better to theri lifestyle goals. Our
secondary objective is to gain insight into the influence of personal
characteristics on the use of the online diary.
Study design
We will conduct a randomized controlled trial of 4 weeks. Subjects fill in
intake questionnaires, concerning demographics and personal characteristics.
They are assigned, double blind, to the test or control group. Concluding, they
fill in an exit survey.
Intervention
Subjects in the test group will be asked to set lifestyle goals, regarding
keeping diary, diet and exercise, and fill in their diet and physical
activities daily in an online diary. A computer assistant will monitor their
diary data and indicate if the data filled in the diary correspond with the
goals. The test group will be compared with the control group, which will be
asked to set lifestyle goals and keep their diet and physical activities daily
in on online diary, but without computer assistance monitoring.
Study burden and risks
To assess if the personal computer assistance contributes to improvement of
self-regulation, we require the participation of overweight subjects for whom
improvement of self-regulation is personally relevant. During the study, the
subject will keep track of their diet and physical activities in an online
diary. This implies we keep a database of the subjects* personal data. Burdens
of the study are that confrontation with being overweight can be distressful.
Also, subjects require having a home computer, which could bias the subjects*
pool. Benefits of the study are that the project follows the existing
development of eHealth, the online diary with computer assistant facilitates
self-regulation, and results of our study can contribute to the development of
scientific research models that support people and increase their self-efficacy
while performing activities in complex task environments.
